The White Witch
Parley Gown

After
the capture of Edmund, Jadis seems to put up a lofty farce of power:
her gown has grown, with wide skirts, and for the first time Jadis
is in almost pure white.

The gown is the basic
template, but with much wider skirts and a train, and a larger
span of the back of the neck "extension", as it were.
It is worn with no fur accessory.

The lower layer of the fabric is a very
light gray, but over that, the felted wool, lace, etc. is white.

Her hair has melted at this point. It's
frozen straight back, not into a bun as first thought, but straight
up and back, the end being twisted around itself. Jadis now has
nine tiny stubs of her ice crown remaining.
